Abstract
The present invention cuts root fertilizer modification method in a kind of meadow steppe area Degraded Leymus chinense clipping pasture, and root is cut, and apply fertilizer to continuous mowing Degenerated Aneurolepidium Chinense angle at 45 ° for many years.It carries out cutting root using agricultural harrow or root cutter, cuts 8 15cm of root depth；20 40cm of width.It applies fertilizer as organic fertilizer or chemical fertilizer.The time for cutting root and fertilising is mid or late May.It is had the beneficial effect that caused by the present invention：Sheep's hay height on meadow steppe significantly increases, and the method has greatly facilitated the level of growth of sheep's hay on meadow steppe.
Description
Technical field
The present invention relates to a kind of grassland improvement methods, particularly a kind of to be directed to meadow steppe area of China Degraded Leymus chinense clipping pasture
Grassland improvement method.
Background technology
China is vast in territory, and continuous mow for many years is caused for Degraded Leymus chinense Grassland, it is short-term how to solve degeneration meadow
Fast quick-recovery is inside difficult to, how to dramatically increase degeneration Grassland Biomass and height, how to improve soil physico-chemical property, improve and is protected
The ecological environment in Degraded Grasslands area is protected, is to have the problem of to be solved.
Invention content
The present invention's exists the technical issues of solution：One kind is provided particular for meadow steppe area Degraded Leymus chinense clipping pasture
Grassland improvement method.
The technology used in the present invention means are as described below.It cuts root fertilizer and changes in a kind of meadow steppe area Degraded Leymus chinense clipping pasture
Good recipe method, to Degenerated Aneurolepidium Chinense, root is cut, and apply fertilizer in angle at 45 °.
It carries out cutting root using agricultural harrow or root cutter, cuts root depth 8-15cm；Width 20-40cm.
It applies fertilizer as organic fertilizer or chemical fertilizer.
The time for cutting root and fertilising is mid or late May.
It is had the beneficial effect that caused by the present invention：Sheep's hay height on meadow steppe significantly increases, and the method greatly promotees
The level of growth of sheep's hay on into meadow steppe.
Specific embodiment
The present invention be directed to meadow steppe area Degraded Leymus chinense clipping pastures to cut root fertilizer modification method, focuses on, to more
Year, root was cut, and apply fertilizer in continuous mowing Degenerated Aneurolepidium Chinense angle at 45 °.Here root of cutting can be using agricultural harrow or root cutter progress
Root is cut, cuts root optimum depth 8-15cm；Width 20-40cm.Here depth refers to the depth sideling cut, and width here refers to cut
Root handle of a knife interval 20-40cm carries out cutting root, this be those skilled in the art will know that.For example, with tractor-drawn 9QP-830 types
The tooth-like meadow of disk break ground root cutter to continuous mowing Degenerated Aneurolepidium Chinense angle at 45 ° for many years to rake twice, cutting root effective depth is
15cm。
It applies fertilizer as organic fertilizer or chemical fertilizer, organic fertilizer is using this area often with organic fertilizer, and amount of application is according to used organic fat
Ingredient is imitated, it is suitable with chemical fertilizer dose.Apply fertilizer nitrogenous fertilizer urea, phosphate fertilizer Diammonium phosphate (DAP).
It is best mid or late May that the time for cutting root and fertilising, which is,.
As shown in table 1, it is comparative example and experimental example.
| Serial number | Handle * | Cut root period | Fertilizer type and dose (kg/hm2) |
| 1 | CK | Mid or late May | / |
| 2 | Cut root | Mid or late May | 0 |
| 3 | Cut root+chemical fertilizer | Mid or late May | Urea 75kg/hm2；Diammonium phosphate (DAP) 45kg/hm2 |
| 4(1) | Cut root+chemical fertilizer | Mid or late May | Urea 150kg/hm2；Diammonium phosphate (DAP) 90kg/hm2 |
| 4(2) | Cut root+chemical fertilizer | Mid or late June | Urea 150kg/hm2；Diammonium phosphate (DAP) 90kg/hm2 |
| 4(3) | Cut root+chemical fertilizer | Mid or late July | Urea 150kg/hm2；Diammonium phosphate (DAP) 90kg/hm2 |
| 5 | Cut root+chemical fertilizer | Mid or late May | Urea 225kg/hm2；Diammonium phosphate (DAP) 135kg/hm2 |
| 6 | Cut root+organic fertilizer | Mid or late May | Available nutrient dosage 63 |
| 7 | Cut root+organic fertilizer | Mid or late May | Available nutrient dosage 127 |
| 8 | Cut root+organic fertilizer | Mid or late May | Available nutrient dosage 190 |
Wherein, serial number 1 is neither cuts root, the reference examples also do not applied fertilizer, and serial number 2 is only cuts the embodiment that root does not apply fertilizer, sequence
Number 3-8 is the embodiment of Qie Gen and fertilising.
It applies fertilizer (or cutting root after can also applying fertilizer) after cutting root, the sheep's hay height on meadow steppe increases 64.2-
122.3%, sheep's hay fresh weight increases 74.4-152.7%, and sheep's hay dry weight increases 49.4-136.5%, and the method greatly facilitates
The level of growth of sheep's hay on meadow steppe.It cuts root+fertilising and dramatically increases group's height (F=2.855, P=0.042) and on the ground life
Object amount (F=3.344, P=0.024).Cut (the urea 225kg/hm of root+to fertilize2；Diammonium phosphate (DAP) 135kg/hm2) it is significantly higher than place
Li Qiegen and do not handle control.
(the urea 225kg/hm of root+to fertilize is cut in the processing of sociales sheep's hay biomass2；Diammonium phosphate (DAP) 135kg/hm2) significantly high
In Qie Gen and control, overall conclusion is cut the height and biomass of root+significantly affect to fertilize group and sociales sheep's hay, is cut
(the urea 225kg/hm of root+to fertilize2；Diammonium phosphate (DAP) 135kg/hm2) processing group's height, group's ground biomass and sheep's hay
Biomass highest is significantly higher than and cuts root+organic fertilizer, Qie Gen and control；Sociales sheep's hay height is cutting root+chemical fertilizer (urea
150kg/hm2；Diammonium phosphate (DAP) 90kg/hm2) highest, it is significantly higher than Qie Gen and control, as shown in table 2 below, wherein serial number 5 is most
It is good.
Table 2 cuts root+fertilising improved test processing COMMUNITY CHARACTERISTICS
On Aneurolepidium Chinense Meadow grassland, arrangement different times cut root+fertilising (fertilizer gradient is identical) experiment, and it is respectively 5 to cut root period
The moon 20, June 20 and July 20.Different times cut root+fertilizer treatment significant impact Aneurolepidium Chinense Meadow psilium and excellent
Height, density, cover degree and the ground biomass of gesture kind.May, 20 Qie Gen+fertilizer treatment significantly improved group's height, life
Object amount and the height of sociales sheep's hay, density, cover degree, ground biomass, for meadow steppe rhizome type sheep's hay cut root it is best when
Phase is mid or late May.
As shown in table 3, different times cut root+fertilising improved test processing COMMUNITY CHARACTERISTICS.
As shown in table 4, Qie Gen is with compareing improved test processing soil moisture and changing bulk density.By to compareing and cutting at root
Moisture and unit weight analysis are managed, result of study shows that different soil cuts soil moisture increase after root, and the soil weight reduces.
Table 4
As shown in table 5, Qie Gen is with compareing improved test processing change of soil nutrient
It cuts root+fertilizer treatment and significantly affects Soil Available content, cut root+fertilising available nitrogen and quick-acting potassium content is dropped
Low, available phosphorus contents slightly increase；Cut root+chemical fertilizer (urea 225kg/hm2；Diammonium phosphate (DAP) 135kg/hm2) total soil nitrogen and complete
Carbon content increases, and full phosphorus and full potassium content reduce；It cuts root+organic fertilizer and significantly improves Population of Actinomycetes and Soil fixed NH_4+
Activity.
Table 5
As shown in table 6, it cuts root+fertilizer treatment and significantly affects edaphon Population of Actinomycetes；Cut root+chemical fertilizer (urea
75kg/hm2；Diammonium phosphate (DAP) 45kg/hm2) fungi and Microbial content are significantly improved, and reduce Population of Actinomycetes；
Cut the activity that root+organic fertilizer significantly improves Population of Actinomycetes and Soil fixed NH_4+.
